FURNACE.

Application filed Gc'tober 7, 1918. Serial No. 257,122.

that heating units may be derived from the' products oi combustion before their iinal escape tothe exhaust flue or chimney. The baille members in this patent are shown proif'iding ay sinuous or tortaous path in a radiating' drum adapted to be installed in a iiue ror chimney and l have 'found that similar battling members can be advantage ously used in a furnace7 particularly the combustion chamber thereof, and by which the efficiency ot the furnace may be materially increased as a heating device.

Reference will now be had Vto the drawing, wherein- Figure 1 is a vertical sectional viewer a 'furnace provided with baille members in accordance with my invention;

Fig, 2 is a horizontal sectional view of the furnace taken on the line 1l-11 of Fig'. 1, and y Fig. 3 is a perspective view of a plurality ot' assembled baille members.

There has been illustrated a convent-tional 'term of furnace or heating apparatus as including a base 1 having; an outer casing or shell 2 provided with a cold air inlet duct or line 3 and hot air distributing ducts or lues 4. ln the casing- Q and on the base 1 is an ash chamber 5 havinga doorway t3, and above the ash chamber andcommunieating); therewith is a tire bor: or pot 7 with vided with heads 14 and the upper ends screwtlireaded to receive nuts 15, said nuts constituting` suitable means for holding the suspension rods in' engagement with the cover 11 and centrally ot' the combustion chamber 9.

@n the suspension rods 1B are spacing sleeves or members 16, and these spacing sleeves or members cooperate with the heads lllof the rods 13 in holding a plurality of baille members 17 spaced apart and in staggered relation relative to one another. Each baiie member is substantially triangular in plan and the arms of said baffle members extend in proximity to the inner walls of the combustion chamber 9. llllith the bathe members staggered a sinuous or tortuous passage is formed in the upper part of the combustion chamber 9, and it is in consequence of this suspended structure that the products of combustion will be retarded in the upper part of the combustion chamber 9 be'jore final escape in the tlue ory chimney 12. lt is therefore possible for the products of combustion to thoroughly heat the walls of the combustion chamber 9 and the air 'circulating' between said combustion chamber and the outer casing 2. Furthermore by retai-dingV the products of combustion., it isi-possible to have ordinary waste `uroducts consumed and reduce the accumulation of soot and the amount of smoke from the I furnace.

members on said tie rods below said flue,A

said baiile members having shortperipheral edges and long concave edges., said baille members being disposedin parallel planes with the short edges thereotV in proximity to walls of the combustion chamber, said tie rods extending through said baille members at the long` concave edges of said baille members and equidistant trom the short peripheral, edges thereof, and sleeves on said tie rods said baile members and a zone dened by the peripheral edges of said bafemembers.

In testimony whereof I my signature inthe presence of two Witnesses. RICHARD 'MRX.
